I COTTON-CLEANING MACHINE.

ratenteaiua e, 1919.

Application filed May 11, 1917. Serial No. 167,960.

To all whom it may concern:

Be it known that we, ARTHUR BRUNE and (Immune H. STONE, citizens of the United States, and residents of Coleyville, in the county of Cottle and State of Texas, have mvented certain new and useful Improvewhich the following is a specification.

This invention relates to new and useful improvements in machines for cleaning cotton, and the primary object of the invention is to provide a device of this character that includes in a single casing, means for cleaning bolly and seed cotton and separating the lint therefrom, and a suction operated draft outlet for drawing the clean cotton from the machine, and feeding the same to the gin stand. j

Another object of the invention is to provide a cotton cleaning machine of this character provided with a suction control outlet, that has a branch associated therewith, to draw the lint from the cotton during the cleaning operation.

A still further object of the invention is to provide a device of this character which is easily and simply constructed, inex ensive to manufacture, and one which will be very efficient in operation.

With these and numerous other objects'in view our invention consists of the novel features of construction, combination and arrangement of parts which will be hereinreferred to and more particularly. pointed out in the specification and claim.

In the accompanying drawings:

Figure 1 is a side elevation of the machine;

Fig. through the same, and V Fig. 3 is a top plan detailed view of a portion of the movable comb that is associated with the cleaning means.

' In describing our invention we shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views. The numeral 1 designates a supporting frame of our machine, which comprises aplu'rality'of upright standards having a main supporting frame 2 carried thereby, which supports the main portion 3 of the casing, which has the heating means for the cotton contained therein. The casing which forms a cover for the whole machine is divided into two parts, the parts 3 containing the heating ments 1n Cotton-Cleaning Machines, of

means, while the part designated by the nu meral- 4 contains the cotton separating means. The inlet for the machine designated 5 is through the end portion 3 of the casing, while theoutlet 6 is connected with the separating means in theportion 4: of said casing.

. The port on?) of the casing contains a pa r of cylindrical heaters? mounted on horizontally extending axes '8 extending through the sides of the casing, and mount ed on the frame 2. These heaters are revolved by any desired means, the same'being adapted to be rotatably connected, as also is a rotatably mounted conveyor 9 disposed adjacent the rear of said heaters. Directly within the inlet 5 of the machine, is

a guide member 10, that directs the cotton.

drawn therein downwardly against the first of the heaters 7. Adjustably mounted with- 1n sald portion 3, andcooperatively related with the beaters 7 is a comb'll, provided" with a projecting handle 12, that permits the ad ustment of the same, said comb com prlsing a plurality of stationary teeth which,

as have been stated are cooperatively related with the projecting teeth 13 on the This will carry the cotton there through, and tend to remove the heavier particles of dirt from thesame, and as said cotton is carried by the teeth. on thebeater through the machine, it passes over arcuate screens 14 positioned beneath heaters, and owing to the action to which said cotton is subjected the dirt, etc., will be shaken there from and dropped into a receptacle 15 that is positioned beneath said screens. The receptacle 15 is provided with an outlet door 16, whereby the dirt may be removed there- As the cotton passes "from the'rear beater 7 it will be engaged by "the rotatably mounted conveyor 9, which comprises a plurality of radially projecting blades 17 mounted on a horizontally extending axis, said blades having their outer ends connected by rubber strips 18, which will gather the cotton and pass the same therethrough and into the portion 1 of the casing, asclearlyshown in Fig. 2 of the drawings.

The portion 4: of the casing in which is positioned the cotton separating means has mounted therein a pair of rotatably mounted disintegrating rolls 19, which have disposed adjacent thereto three picker wheels 20, which. cooperatively related. there with, one picker Wheel being disposed adjacent one of the disintegrating rolls, while a pair of picker wheels are disposed adjacent the opposite roll. The picker wheels and saws are disposed in vertical alinement, and guide means 21 are associated therewith, to direct the passage of cotton therethrough. After the burs have been removed from the cotton through the operation of the rolls and picker wheels, the same drop to the bottom of the guide portions 21, and pass through'an outlet 22 in the bottom thereof. The cotton will be carried by the rolls into engagement with a brush 22, that is also rotatably mounted through the portion 4, and hence to the outlet 6, that is provided with suction operated means associated therewith, to readily draw the cotton therefrom and carry it through the pipe 23 to the stand.

A branch pipe 24 is connected with the suction control outlet 6, said branch extending forwardly and along the top of the portion 3 of thecasing, and having its forward end communicating therewith, said communicating portion having a wire screen 25 positioned therein, as clearly shown in Fig.

' 20f the drawings. This is disposed directly over the cotton beating means within the portion 3 of the casing, and as the cotton is subjected to the action of thebeaters, it is obvious that lint, etc., will rise therefrom,

and as'the suction operated means is connected with the pipe 24, said lint will be drawn therethrough, and through the outlet pipe 23. This affords an easilyand simply constructed mechanism for withdrawing the lint from the cotton, without wasting the same.

In operation when the cotton is fed through the inlet 5 to the portion 3 of the casing, the same will be subjected to the ac tion of the beaters 7, which will thoroughly cleanse the same, and remove all loose dirt therefrom, said dirt dropping through the screens '14 into-the receptacle 15. The cot ton is passed by the rotatably mounted beaters-to the conveyer 17, and thence carried by the same downwardly and dropped into the portion 4 of said casing. Within this portion, the cotton is subjected to the separating operation, and the burs and trash are removed therefrom by the cooperation of the rolls and picker wheels. After the cotton has been separated, the same is carried over the brush 22, and out through the suction Copies control outlet 6. The branch pipe 24: whiclf is connected with the cleaning means, will remove lint from the cotton and also carry the same to the outlet.

The various heaters, and rotatably mounted rolls, picker wheels, brush'and conveyer are adapted to be connected by a chain gearing, or any other desired type, not shown, and all of the same operated by a single motor. However this is optional, and any desired means may be employed for rotating these parts. The operation of this device is automatic, as when the cotton is fed to the machine, it is carried therethrough, and to the stand in a manner hereinbefore fully described. The heating and separating operations are efficiently carried out, and the cotton will be thoroughly cleaned when drawn into the outlet 6, where it is carried to the gin stand.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction, and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while we have described the principle of operation of the invention, together with the device which wenow consider to be the best embodiment thereof, we desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.- 7

Having fully described our invention,

what we claim as new, and desire to secure by Letters Patent is:

A cotton cleaning machine comprising a casing, a plurality of horizontally arranged rotatable heaters therein over which the cotton is adapted to pass, rotatable picker wheels arranged in the casing beyond said boaters, disintegrating rolls positioned in proximity to said picker wheels, a secondary housing receiving the picker wheels and disintegrating rolls, and a pneumatic conveyer having a substantially V-shaped branch eX- tending into the casing, one extremity of the branch communicating with the secondary casing and the other extremity thereof communicating with that portion of the casing of the heaters.

In testimony whereof, we affix our signatures hereto.

ARTHUR BRUNE. CHARLES H. STONE.
